Patent number: 9559969Abstract: Systems and methods are described for source-aware shaping of network traffic in a communications system. Embodiments can manage resource congestion within a communications network by preferentially adjusting certain types of traffic on a per-subscriber and/or per-application basis. For example, a subscriber can receive various types of traffic in respective streams, and the streams can be identified according to whether they carry adaptive traffic. When a congestion condition is detected, one or more of the identified streams can be squeezed or expanded, which can cause an associated content source to automatically adapt communication of the adaptive traffic (e.g., its quality) to the reduced or expanded capacity. Selectively squeezing those streams identified as adaptive can appreciably mitigate congestion, while maintaining a desired level of network performance for the subscriber.Type: GrantFiled: April 11, 2014Date of Patent: January 31, 2017Assignee: ViaSat Inc.Inventors: Kristi Jaska, James Esserman

Patent number: 9553650Abstract: Disclosed herein is a system, apparatus, and method for using an antenna system comprising individually configurable antenna circuitries in a wireless network device to simulate the standard MU-MIMO transmissions as specified in the IEEE 802.11ac standard with antenna beamforming. The individually configurable antenna circuitries can be configured to transmit radio frequency (RF) signals with specific radiation patterns including directional beam patterns. Client devices may be grouped and antenna circuitries may be configured in such a way as to minimize inter-user interference. Frequent sounding-channel state feedback cycles and associated overhead are obviated with antenna beamforming, and no change to standard-compliant client devices is necessary. A better overall performance compared to MU-MIMO based on DSP-based beamforming as specified in the IEEE 802.11ac standard is expected.Type: GrantFiled: April 18, 2014Date of Patent: January 24, 2017Assignee: Aruba Networks, Inc.Inventor: Subburajan Ponnuswamy
